Pugnellus Crassicostatus

Original Description of Pugnellus crassicostatus by Noetling, 1915, p. 60:

"The shell is fusiform, accuminate at each end, and consists of five or six volutions, forming rather a low spire; the last whorl, which is ventricose, occupies at least three quarters of the total height of 45 mm. and terminates in a tolerably long canal. The outer lip is much thickened, and expanded into a roundish wing which is bent somewhat backwards. The ornamentation consists of strong, rounded S-shaped ribs on the last whorl, which begin near the suture and disappear about half way across the whorl. Aperture scarcely seen, apparently longitudinal and narrow.
